Mhash Functions

简介

These functions are intended to work with » mhash. Mhash can be used to create checksums, message digests, message authentication codes, and more.

This is an interface to the mhash library. mhash supports a wide variety of hash algorithms such as MD5, SHA1, GOST, and many others. For a complete list of supported hashes, refer to the documentation of mhash. The general rule is that you can access the hash algorithm from PHP with MHASH_HASHNAME. For example, to access TIGER you use the PHP constant MHASH_TIGER.

Note: 本扩展已被移动到 » PECL 库中且自以下版本起不再被绑定到 PHP 中：5.3.0. This extension is obsoleted by Hash.

需求

To use it, download the mhash distribution from » its web site and follow the included installation instructions.

安装

You need to compile PHP with the --with-mhash[=DIR] parameter to enable this extension. DIR is the mhash install directory.

运行时配置

本扩展模块在 php.ini 中未定义任何配置选项。

资源类型

本扩展模块未定义任何资源类型。

预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

Here is a list of hashes which are currently supported by mhash. If a hash is not listed here, but is listed by mhash as supported, you can safely assume that this documentation is outdated.

MHASH_ADLER32
MHASH_CRC32
MHASH_CRC32B
MHASH_GOST
MHASH_HAVAL128
MHASH_HAVAL160
MHASH_HAVAL192
MHASH_HAVAL256
MHASH_MD4
MHASH_MD5
MHASH_RIPEMD160
MHASH_SHA1
MHASH_SHA256
MHASH_TIGER
MHASH_TIGER128
MHASH_TIGER160

范例

Example#1 Compute the MD5 digest and hmac and print it out as hex


<?php
$input = "what do ya want for nothing?";
$hash = mhash(MHASH_MD5, $input);
echo "The hash is " . bin2hex($hash) . "<br />\n";
$hash = mhash(MHASH_MD5, $input, "Jefe");
echo "The hmac is " . bin2hex($hash) . "<br />\n";
?>

This will produce:

The hash is d03cb659cbf9192dcd066272249f8412 
The hmac is 750c783e6ab0b503eaa86e310a5db738

mhash_count — Get the highest available hash id
mhash_get_block_size — Get the block size of the specified hash
mhash_get_hash_name — Get the name of the specified hash
mhash_keygen_s2k — Generates a key
mhash — Compute hash
